Familial Hemiplegic Migraine (FHM) is a rare genetic condition associated with severe migraines. It is characterized by temporary paralysis or weakness on one side of the body before or during a migraine attack. FHM is caused by mutations in specific genes that code for proteins involved in neurotransmitter control and brain function. These genetic mutations disrupt the normal functioning of neurotransmitters, leading to the symptoms of FHM.
Scientific studies, with support from patient advocacy groups and genetic testing centers, have identified several genes associated with FHM. These genes include CACNA1A, ATP1A2, SCN1A, and PRRT2, among others. Mutations in these genes have also been linked to other rare neurological conditions, providing further evidence of the genetic basis of FHM.
The frequency of FHM is relatively low, and it usually has a strong familial inheritance pattern, meaning it is passed down through generations within certain families. The exact mechanisms for how the mutations in these genes cause FHM are not yet fully understood, but ongoing research is shedding light on the complex interplay between the genetic and environmental factors that contribute to the development of this condition.
For patients and families affected by FHM, there are resources available to learn more about the condition and find support. The OMIM database and PubMed, a scientific article database, provide additional information on the genes associated with FHM and the diseases they are linked to. ClinicalTrials.gov is also a valuable resource for finding clinical trials related to FHM and its treatment.
Understanding the genetic causes and underlying mechanisms of FHM is crucial for developing targeted treatments and interventions. By learning more about this rare condition, researchers and clinicians can provide better support and care for patients and families affected by FHM.

Frequency
Familial hemiplegic migraine (FHM) is a rare neurological condition characterized by severe migraines that are accompanied by temporary paralysis or weakness on one side of the body.
The frequency of FHM episodes varies among individuals, ranging from several attacks per month to only a few episodes in a lifetime. The severity and duration of the attacks also vary, as some individuals may experience mild symptoms that resolve within a few hours, while others may have more severe symptoms that last for several days.
Research has shown that FHM is caused by genetic mutations, with mutations in the CACNA1A, ATP1A2, and SCN1A genes being the most commonly identified in affected individuals. These genes provide instructions for making proteins that play a role in regulating the flow of calcium, sodium, and potassium ions in brain cells. Disruptions in these ion channels can lead to abnormal brain cell activity and the development of migraines.
Further information about the genes associated with FHM can be found in the OMIM database and other scientific articles referenced on PubMed.
Inheritance of FHM follows an autosomal dominant pattern, meaning that a person only needs to inherit the mutated gene from one parent to develop the condition. However, the specific mechanisms underlying the development of FHM are still not fully understood, and research is ongoing to learn more about the genetic and environmental factors that contribute to the condition.
In addition to the genetic causes, certain triggers, such as stress, hormonal changes, certain foods, and physical exertion, can also contribute to the frequency and severity of FHM attacks. Identifying and avoiding these triggers may help reduce the occurrence of migraines in affected individuals.
ClinicalTrials.gov provides information on ongoing research studies and clinical trials related to FHM, which can provide additional support and treatment options for patients. Furthermore, advocacy organizations and support groups can also provide resources and support for individuals and families affected by FHM.
